Aqueous outflow via the conventional outflow pathway is dependent on the pressure gradient between intraocular pressure (IOP) and episcleral venous pressure (EVP). Elevated IOP resulting from increased EVP is a well-known complication of arteriovenous fistulas, which are usually between the carotid artery and the cavernous sinus. Arteriovenous malformations usually occur spontaneously, after a trauma or from iatrogenic causes, and they manifest with findings of chemosis, dilatation of the conjunctival vessels, exophthalmos, and extraocular motility limitation. In this study, we present a case of elevated IOP due to facial arteriovenous malformations following a functional neck dissection surgery that caused intraocular pressure elevation.

Arteriovenous malformations (AVM) are congenital vascular lesions fed by arterial feeders originating from branches of the internal carotid artery (ICA) or vertebrobasilar artery. We experienced unique AVMs arising in the midline Galenic region, receiving blood supply from the ICA/vertebral artery systems and the external carotid artery system. We retrospectively reviewed data on eight patients who had an AVM arising in the Galenic region and were treated in the University of Tokyo Hospital between 1990 and 2019. The median age at diagnosis was 62 years. Three cases (38%) presented with obstructive hydrocephalus due to aqueduct obstruction caused by an engorged vein of Galen. In all cases, feeders from dural arteries were present and the vein of Galen was the primary drainer. All patients underwent stereotactic radiosurgery. Five patients were followed for > two years; nidus obliteration was confirmed in one, and > 75% shrinkage was confirmed in three, while one patient died due to hemorrhage. Altogether, AVMs arising in the Galenic region are rare and exhibit several peculiar characteristics including the presence of dural feeders, an older age at presentation and presentation with obstructive hydrocephalus.

Carotid duplex sonography is a useful method for evaluation of dural arteriovenous fistulas. The resistance index of the external carotid artery has been reported to correlate with the efficacy of treatment and recurrence or aggravation of dural arteriovenous fistulas. Herein, we describe a case of dural arteriovenous fistulas mainly supplied by the occipital artery and show that the resistance index of the occipital artery was more sensitive than that of the external carotid artery. To the best of our knowledge, this is the first report to describe the feasibility of occipital artery detection by carotid duplex sonography and clinical application of the resistance index of the occipital artery for dural arteriovenous fistulas.

Treatment Considerations

Background: In rare circumstances, brain arteriovenous malformations (BAVMs) can recruit a transdural blood supply (TBS). The clinical and radiologic characteristics of BAVMs with a TBS are poorly understood.Methods: A retrospective review of the medical records was conducted for adult patients who were admitted for BAVMs from Jan 2013 to Dec 2019. TBSs for BAVMs were divided into 3 types: (1) unilateral TBSs from the external carotid artery (ECA) and/or meningeal branch of the vertebral artery (VA); (2) bilateral TBSs from the ECA and/or meningeal branch of the VA; and (3) meningohypophyseal trunk TBSs of the internal carotid artery.Results: Four hundred and twenty-eight patients were diagnosed with BAVMs during the study period, of whom 30 (7.0%, 30/428) were identified as having a TBS. Type 1, type 2, and type 3 TBSs were identified in 21 (70%, 21/30), 7 (23.3%, 7/30), and 2 (6.7%, 2/30) patients, respectively. Six (20%, 6/30) patients were conservatively managed. Twelve (40%, 12/30) patients underwent endovascular treatment (EVT) of the BAVM through non-TBS feeders. Eight (26.8%, 8/30) patients underwent EVT of the BAVM both through the TBS and non-TBS feeders. The modified Rankin Scale scores at the 3-month follow-up were 0, 1, 2, 4, and 5 in 24 (80%, 24/30), 2 (6.7%, 2/30), 2 (6.7%, 2/30), 1 (3.3%, 1/30), and 1 (3.3%, 1/30) patients, respectively. Good short-term recovery was achieved in 86.7% (26/30) of the patients. The size of the BAVMs with a TBS was larger than that of BAVMs without a TBS. Patients with higher Spetzler-Martin grades tended to have a TBS. No statistical difference was noted between the patients with and without a TBS with regard to age, sex, location, or concurrent aneurysms.Conclusions: This study showed that a TBS was likely to develop in patients with larger BAVMs and that a TBS was likely to be located in the temporal lobe in patients BAVMs with higher SM grades. Weak structures were the primary targets of management. In addition, a BAVM could be embolized via the TBS.

Dural Arteriovenous Fistulas

Abstract The purpose of our article is to present the results of our treatment of dural arteriovenous fistula of the cavernous sinus by glue embolization of the external carotid artery feeders. By this case presentation we try to clarify the clinical course, with the dural carotid cavernous fistula (CCF), characterizing a pallet of symptoms, paying special attention to radiological finding and endovascular treatment. Dural arteriovenous fistulas represent 10% to 15% of all intracranial arteriovenous malformations (A. Fox, G. Duckwiler, “Dural Arteriovenous Fistula,” presented at the annual meeting of the American Society of Neuroradiology, St Louis, Mo, June 1992). Dural arteriovenous fistulas are rare clinical situation, especially examples involving the cavernous sinus. Most dural fistulas are acquired conditions, typically occurring in postmenopausal women, but sometimes in other patients in association with other condition [1,3]. These dural fistulas are most often “spontaneous” cavernous carotid shunts (usually low-flow) [2, 4, 5], usually related to a past trauma or surgery. The classical triad, represented by pulsating exophthalmos, conjunctival chemosis, and pulsatile-tinnitus are well-known clinical symptoms of these lesions but are not necessary present in the majority of the patients as first indicators. The anatomy of these vascular malformations consists of multiple arterial feeders flowing into cavernous sinus. The arterial feeders are usually meningeal branches arising from the internal carotid artery (ICA) or the external carotid artery (ECA). However, there are few reports of large series [1], and the clinical entity is not widely known. The purpose of this paper is to present a clinical case of a patient with dural cavernous sinus fistulae, clarify the clinical symptoms course and special attention to results of endovascular treatment.

Apparent Reason

Objective pulsatile tinnitus on a vascular basis is a relatively uncommon auditory phenomenon. There are other forms of objective tinnitus which will not be covered in this discussion. The most common lesions are arteriovenous malformations near the temporal bone which are branches of the external carotid artery, such as the occipital artery, to the transverse or sigmoid sinus. Diagnostically, a patient can be entirely asymptomatic except for a pulse-synchronous objective tinnitus in one ear. There is usually no associated hearing loss, vertigo, imbalance or pressure. A sense of fullness may not be a constant problem but may be intermittent. The objective pulsatile tinnitus may not be a constant problem but may come and go for no apparent reason.
